BOTTLE S'IGPPER.

Application filed March 31, 1921. Serial No. 457,552.

To all whom, it may concern: I Be it known that we, WILLIAM M. Goon- WIN and LELAND E. PHILLIPS, of Central Square and Brewerton, respectively, in the counties of Oswego and Onondaga, in the State of New York, have invented new and useful Improvements in Bottle Stoppers, of which the following, taken in connection with the accompanying drawings, is a. full, clear, and exact description.

This invention relates to bottle stoppers and is particularly useful in connection with that type of bottle having an annular bead around the mouth thereof, the main object being to provide a simple and eflicient device whereby a bottle cap or stopper .may be easily and quickly clamped in place to form a liquid and air tight joint to remain onthe bottle until such time as may be desired to.

Fig. 1 is a longitudinal vertical sectional view of the bottle-top and my improved clamping device therefor, a portion of the bottle being shown in elevation.

Fig.2 is a top plan of the same device and the adjacent end of the bottle.

' modified form of the clamping device as Fig. 3 is a side elevation of the clamping device shown in Fig. 1.

Fig. 4 is an inverted plan of a detached clamping device omitting the top.

Fig. 5 is-a sectional view of a, slightly used in connection with a stopper or cork which enters the bottle, the latter beingv shown in section. I

Fig. 6 1s a detail sectional view of a portion of one side of the clamping device showing the cam projection thereon cooperating with the handle of the cam-shaft for tightening the aws of the clamp on the cap ofthe bottle. I j

The bottleas -A is provided with the usual. annular bead -a surrounding the mouth thereof for receiving and supporting a suitable cap b, as shown in Fig. 1 or,

s as shown in Fig. 5.

The clamping device for holding the stopper in place comprises a bow-shaped mem ber 1- preferably of spring steel having its ends bent toward each other in substan tially the same plane to form opposed jaws 2 the inner faces of which are concaved at 3- to conform to the curvature of the neck of the bottle just below the bead w where the bottle.

The bow or U-shaped member -1 is preferably made of comparatively thin flat bar of sheet metal as spring steel of less jaws are adapted to engage the Width than the diameter of the mouth ofthe bottle and intended to normally spring the jaws to move outwardly when said jaws are released from gripping engagement with the neck of the bottle, as for example in releasing the cork to facilitate the removal of the clamping device. y The opposite armsof the bow or U-shaped member 1-- are provided with transversely alined apertures l to form suitable journal-bearings for a cam-shaft 5- which isjournaled in and extends beyond the opposite arms ofsaid, member and has its central portion provided with a lateral arm-set-6- forming an eccentric for engaging the. cap b, said shaft being extended diametrically across the top or mouth of the bottle A to cause its cam or extending portion 6 to engage the central portion of said cap, when the shaft is ad justed to its locking position, it being understood that the distance between the shoulders or jaws -2. and shaft 5 is approximately equal to or slightly greater than the distance between the under side of the feed -a and upper faces otthe cap l-- to cause the cam --(l-- to impinge tightly against the cap when the jaws ---2-'- are engaged with the under side of the bead and the cam or extending portion -6 is adjusted to its locking position, as shown by full lines in Fig. 1.

The opposite ends of the cam-shaft -5 are offset in the same direction and substantially at right angles'to the axis thereof, one of offset ends as 7- being relatively short to engage the outer face of the adj acent arm of the bow-shape member .1-,

while the other, offset end as 8 is con The portion of the opposite arms of the bow or U-shaped member 1- just above the opening 4: are pressed inwardly beyond the portions of the arms below the shaft 5 to form recesses -10- for receiving the adjacent portions of the offsets -7 and -8 when the cam-shaft is rocked to its releasing position, as shown by dotted lines in Fig. 1, and thereby permitting the jaws 2 to swing outwardly out of engagement with the underside of the head a-, whereupon the entire clamping device may be withdrawn upwardly from the bottle, the walls of 'said recesses being curved transversely or concaved to form cam-faces against which the offset portions -7 and -8- of the cam-shaft may rock when the cam-shaft isadjusted to its looking position for tightening jaws from the neck of the bottle directly beneath the bead If desired, however, a portion of one or both of the opposite arms of the bow or U-shaped member 1 may be pressed outwardly, as shown in Fig. 6 to form a cam member -11- projecting beyond the adjacent portions of the arms and against which one or both ofthe offsets -7 or 8- may ride to tightly clamp the jaws 2 against the mouth of the bottle, or rather against the periphery of the neck directly beneath the bead a'.

In Fig. 5 is shown a stopper b adapted to enter the mouth of'the bottle and to engage the end face thereof and is provided with an outwardly projecting lug -l2-- having a transverse aperture -13 for receiving the cam portion 6 ofthe cam-shaft 5--, thereby attaching the stopper to the cam shaft so that when'the latter. is adjustedto its releasing position, it will withdraw the stopper from the bottle simultaneously with the release of the jaws 2- from engagement with the periphery of the neck of the bottle directly beneaththe bead -a-, otherwise the construction is very similar to that previously described.

lVhenthe. jaws -2- are released from engagement with the neck of the bottle, as shown in Fig. 1, they will spring outwardly beyond the bead -a and directly under the adjacent edges of the cap b so that whenthe clamping member -1- is. with drawn, the jaws .2' will engage the lower edge of the cap and release the same from.

its closed position.

In clamping the cap in place upon the bottle, it is simply necessary to clamp the bow or U-shaped'member downwardly over the mouth of the bottle, thereby causing the jaws 2- to ride against the periphery of the cap -buntil they spring over and around and beneath the bead (a, whereupon the cam-shaft 5-- may be rocked from the dotted position in Fig. 1 to the position shown by fulllines to cause. the cam -6 to impinge against the to of the cap b and thereby to firmly ho d the latter in place during which operation the. offset portions -7 and 8- ride against the outer faces of the adjacent portions of the arms of the bow-shaped member --1 to close the jaws inwardly and hold them against'swinging apart when engaged with the neck of the bottle at the under side of the bead.

What I claim is: I

1. 'A bottle stopper comprisinga cap, a U- shaped'clampingmember having its ends free to move toward and-from each other and provided with inturned jaws for gripping and releasing the neck of a bottle, the'opposite arms of said member being provided with transversely alined apertures and outwardly projecting cams adjacent the aper- .tures, a shaftjournaled in said'apertures and provided with a lateral offset for engaging the cap and having its ends offset for engaging the cams on said arms.

2. A bottle stopper comprising a cap, a U-shaped clamping member of flat springmetal having its opposite arms provided with inturned jaws movable toward and from each other for gripping and releasing the periphery and releasing .of'a bottle, said arms beingtensionedto open the aws away from the bottle, and a cam-shaft journaled on 'saidarms and having its cam engagingsaid cap to hold the latter inplacef l A bottle stopper comprising a cap, a U-shaped clamping member of flat springmetal having the ends-of its opposite arms bent toward each other to form gripping. jaws for engaging opposite sides of the neck of'a bottle, a cam on the outer face of one 105 of the arms near the adjacent jaw, av shaft j ournaled in the opposite arms of said memher and provided with an offset portion at one side of its axis of movement for engaging the cap when the shaftis adjusted to one 110 position and for releasing the cap when adjusted to another position, and a crank arm on theshaft for engaging saidram to tighten. the jaws onflthe bottle.

4L. A. bottle stopper comprising a cap, a 115 bow-shaped clamping member having its opposite arms provided with inturned rjaws movable toward and from each other for gripping and releasing the neck of a bottle, and a" shaft journaled in said arms and pro- 120 vided with means forv closing and opening I the cap'when rotated, said clamping member and shaft having cooperative means. for moving the jaws toward each other when closing the cap and for releasing said jaws whenthe cap isopen.

5. A bottle stopper comprising a cap, a bow-shaped clamping member having opposite arms provided with inturned jaws movable toward and from each other for gripping and releasing a bottle, a shaft journaled in the opposite arms of said member and having its ends offset in the same direction for engaging the outer faces of said arms, one of the offset portions being of greater length than the other to form. a handie by which the shaft may be rotated, said shaft having its intermediate portion offset laterally for engaging the cap when the shaft is adjusted to one position, and a camface on one of said arms against which the adjacent offset portion of the shaft is adapted to ride for tightening and releasing the jaws of the arms upon and from the bottle.

In witness whereof we have hereunto set our hands this 28th da of March 1921.
